The S8745-01 is a silicon photodiode with integrated operational amplifier, feedback resistance of 1 GΩ, and feedback capacitance of 5 pF, packaged in a TO-5 case with a 2.4 × 2.4 mm photosensitive area. It operates from 190 to 1100 nm, with peak sensitivity at 960 nm and a noise equivalent power of 11 fW/Hz¹/² at peak wavelength and 10 Hz. The device has an output offset voltage of ±4 mV, a cutoff frequency of 32 Hz, and a 13 V output voltage swing. Supply current is ±0.3 mA, and it operates from -20 to +60 °C with ±20 V supply voltage. The photosensitive area is internally connected to GND for EMC noise immunity, and the package includes a shielding effect. Gain can be varied using an external feedback resistor.
Photodiode and preamp integrated with feedback resistance and capacitance
This is a low-noise sensor consisting of Si photodiode, op amp, feedback resistance and capacitance, all integrated into a small package. By simply connecting to a power supply, it can be used in low-light-level measurement such as analytical equipment and measurement equipment. The photosensitive area of the photodiode is internally connected to the GND terminal making it highly resistant to EMC noise.
